Description

Technical Field

[0001] This application relates to the field of communication technologies, and in particular, to communication methods and related devices. Background Art

[0002] With the development of wireless networks and the evolution of service requirements, there are a large number of Internet of Things (IoT) nodes in the network. IoT nodes are usually small in size and cannot carry large-capacity batteries, facing the problem of short standby life. Implementing wireless energy transfer (WPT) through a base station is one of the important ways to solve the short battery life of IoT nodes.

[0003] In the technical solution of implementing WPT through a base station to solve the short battery life of IoT nodes, the base station sends a wireless signal. After the IoT node receives the wireless signal sent by the base station, it can obtain the energy in the wireless signal to charge the battery.

[0004] However, the energy consumption of the base station is relatively large. Therefore, how to reduce the energy consumption of the base station is a problem that needs to be solved. Summary of the Invention

[0005] This application provides a communication method, a communication device, and a communication system, which helps to save the energy consumption of network devices for charging terminals.

[0006] In a first aspect, this application provides a communication method, which includes: sending first information to a network device, where the first information indicates a first intensity, and the first intensity is the intensity of at least one type of energy in the environment where the terminal is located; receiving a charging signal sent by the network device based on the first information.

[0007] This method can be executed by a terminal or a communication device applied in the terminal. Or it can be said that this method can be applied to the terminal.

[0008] In this method, sending information indicating the intensity of one or more types of energy in the environment where the terminal is located to the network device helps the network device to know the intensity of the energy that the terminal can obtain from the environment, thereby helping the network device to determine a charging signal with an appropriate power based on the intensity of the environmental energy, and further helping to reduce the energy consumption of the network device for charging the terminal.

[0009] In some possible implementation manners of this method, the at least one type of energy may include at least one of the following energies: radio frequency energy, light energy, thermal energy, or vibration energy.

[0010] For the first information indicating the intensity of the at least one type of energy, in some possible implementations, the first information may include at least one energy information, and the at least one energy information corresponds to the at least one type of energy one by one. Each energy information in the at least one energy information indicates the intensity of a corresponding type of energy. That is to say, the intensity of each type of energy is indicated separately.

[0011] Indicating each type of energy separately enables the network device to clearly know the intensity of each type of energy, thereby obtaining the intensity distribution of each type of energy, predicting the energy arrival time in advance, and optimizing resource scheduling.

[0012] For the first information indicating the intensity of the at least one type of energy, in some other possible implementations, the first information indicates the total intensity of all types of energy in the at least one type of energy. Indicating the total intensity can reduce the amount of information reported, reduce the transmission time, and save power.

[0013] In some possible implementations of this method, the first information further indicates the duration of the at least one type of energy. This implementation helps the network device accurately know the charging power that the at least one type of energy can provide for the terminal based on the duration of the at least one type of energy, thereby helping the network device accurately determine a charging signal with appropriate power, and further helping to reduce the energy consumption of the network device for charging the terminal.

[0014] For the first information indicating the duration of the at least one type of energy, in some possible implementations, the first information may include at least one duration information, and the at least one duration information corresponds to the at least one type of energy one by one. Each duration information in the at least one duration information indicates the duration of a corresponding type of energy. That is to say, the duration of each type of energy is indicated separately.

[0015] Indicating the duration of each type of energy separately enables the network device to clearly know the duration of the intensity of each type of energy, thereby obtaining the intensity distribution of each type of energy over time, predicting the energy arrival time in advance, and optimizing resource scheduling.

[0016] For the first information indicating the duration of the at least one type of energy, in some other possible implementations, the first information indicates a duration for all types of energy in the at least one type of energy.

[0017] For example, the duration indicated by the first information may be the duration of the energy with the maximum intensity in the at least one type of energy, may be the shortest duration among the durations corresponding to the at least one type of energy respectively, may be the average duration of the durations corresponding to the at least one type of energy respectively, or may be the total duration of the type of energy with the strongest intensity in the at least one type of energy.

[0018] In some possible implementation manners of the method, the first information further indicates the type of each type of energy among the at least one type of energy. In this way, it is beneficial for the network device to optimize the scheduling of charging resources. For example, since vibration energy is prone to disappear, more charging resources can be pre-allocated. It is also beneficial for the distribution of the network device or each type of energy in terms of time, predicting the energy arrival time in advance, and optimizing resource scheduling.

[0019] In some possible implementation manners of the method, the first information indicates both the duration of the at least one type of energy and the type of each type of energy among the at least one type of energy.

[0020] If the at least one type of energy includes radio frequency energy, in some possible implementation manners of the method, the first information further indicates the frequency band of the radio frequency energy. In this way, it is beneficial for the network device to know the distribution of each type of energy with different frequency points in terms of time, predict the energy arrival time in advance, and optimize resource scheduling.

[0021] For the case where the first information further indicates the frequency band of the radio frequency energy, in some possible implementation manners, the first information may indicate the total intensity of the radio frequency energy of all frequency bands, or the first information may separately indicate the intensity of the radio frequency energy of each frequency band.

[0022] The intensity of the radio frequency energy of each frequency band is separately indicated, which enables the network device to clearly know the intensity of each type of energy, thereby knowing the intensity distribution of the radio frequency energy of each frequency band, predicting the energy arrival time in advance, and optimizing resource scheduling.

[0023] Indicating the total intensity of the radio frequency energy of multiple frequency bands can reduce the amount of information reported, reduce the transmission time, and save power.

[0024] In some possible implementation manners of the method, before sending the first information to the network device, the method further includes: receiving second information from the network device, where the second information is used to determine the resources for the terminal to collect ambient energy.

[0025] Optionally, at the resources for the terminal to collect ambient energy indicated by the second information, the network device does not send a signal. In this way, the ambient energy collected by the terminal at this resource does not include the radio frequency energy sent by the network device. In this way, it can be avoided that the radio frequency energy reported by the terminal includes the radio frequency energy provided by this network device, which helps the network device accurately know the energy that the environment can provide for the terminal, and further helps the network device accurately determine the energy it needs to provide for the terminal.

[0026] For example, the resource includes time domain resources, and the network device does not send a signal on all or part of the frequency domain resources at this time domain resource.

[0027] For another example, the resource includes time-domain resources and frequency-domain resources, and the network device does not transmit signals at the time-frequency resources and the frequency-domain resources.

[0028] For the resource for the terminal to collect ambient energy, in some possible implementation manners, the resource may include multiple time-domain resources, and different time-domain resources among the multiple time-domain resources correspond to different frequency-domain resources. In this implementation manner, because different time-domain resources correspond to different frequency-domain resources, that is to say, the network device does not transmit signals at different times on different frequency-domain resources, or it can be said that at least some of the frequency-domain resources at each of these time-domain resources are available for the network device to transmit signals. Therefore, the communication of the network device will not be affected because the terminal accurately collects ambient energy.

[0029] In some possible implementation manners of the method, before receiving the second information from the network device, the method further includes: sending third information to the network device, where the third information is used to instruct the terminal to request the network device to perform radio frequency energy measurement.

[0030] That is to say, the terminal notifies the network device that the terminal needs to perform radio frequency energy measurement so that the network device can configure resources for the terminal to collect ambient energy.

[0031] Optionally, the third information may also be understood as being used to instruct the terminal to request the network device to perform ambient energy measurement, or the third information may also be understood as being used to request resources for the terminal to collect ambient energy.

[0032] For the third information, in some possible implementation manners, the third information further indicates the operating frequency band of the terminal. This helps to avoid the network device configuring invalid resources for the terminal to collect ambient energy and avoid waste of signaling overhead.

[0033] In some possible implementation manners of the method, the method further includes: sending fourth information to the network device, where the fourth information indicates a second intensity, and the second intensity is the intensity of at least one type of energy in the environment where the terminal is located, and the measurement period of the second intensity is after the measurement period of the first intensity.

[0034] That is to say, the terminal can update the intensity of the energy in its environment to the network device, which helps the network device determine a charging signal that can both meet the charging needs of the terminal and save the energy consumption of the network device based on the updated intensity.

[0035] In some possible implementation manners of the method, the fourth information indicates the second intensity, including: the fourth information indicates the difference between the second intensity and the first intensity.

[0036] In this implementation manner, the fourth information informs the network device of the second intensity by indicating the difference between the second intensity and the first intensity. Compared with directly indicating the second intensity, since the difference is smaller than the second intensity, signaling overhead can be saved.

[0037] In some possible implementation manners of this method, sending the fourth information to the network device includes: when the absolute value of the difference between the second intensity and the first intensity is greater than or equal to a threshold, sending the fourth information to the network device. In other words, when the absolute value of the difference between the second intensity and the first intensity is less than the threshold, the fourth information is not sent to the network device.

[0038] In some possible implementation manners of this method, the method further includes: receiving fifth information from the network device, where the fifth information is used to configure the threshold.

[0039] The level of the threshold can determine the feedback frequency. The higher the threshold, the smaller the feedback frequency, which can save terminal energy, but the real-time update of the environmental energy information also decreases. The network device configures the threshold, which can adjust the update frequency of the environmental energy information, making it possible to balance the real-time update of the environmental energy information and the energy consumption of the terminal for feedback on the environmental energy information, which is relatively reasonable. For example, the threshold is increased when the environmental energy fluctuates little, and decreased when the fluctuation is large.

[0040] In some possible implementation manners of this method, the resources used to send the fourth information are pre-configured or pre-defined.

[0041] In some possible implementation manners of this method, the method further includes: receiving sixth information from the network device, where the sixth information indicates the end of charging. In this way, on the one hand, the terminal can stop reporting the relevant information of the environmental energy to the network device based on the indication of the sixth information, avoiding waste of signaling overhead; on the other hand, the terminal can release the resources allocated for reporting the relevant information of the environmental energy for other purposes, improving resource utilization.

[0042] In some possible implementation manners of this method, the method further includes: sending seventh information to the network device, where the seventh information indicates the end of charging. In this way, the network device can release the resources allocated for reporting the relevant information of the environmental energy for other purposes, improving resource utilization.

[0043] In a second aspect, the present application provides a communication method, where the method includes: receiving first information from a terminal, where the first information indicates a first intensity, and the first intensity is the intensity of at least one type of energy in the environment where the terminal is located; sending a charging signal to the terminal according to the first information.

[0044] This method can be executed by a network device or a communication device applied in the network device. Or it can be said that this method can be applied to the network device.

[0045] In this method, the network device obtains the intensity of one or more types of energy in the environment where the terminal is located, which helps the network device to obtain the intensity of the energy that the terminal can obtain from the environment, thereby helping the network device to determine a charging signal with appropriate power based on the intensity of the environmental energy, and further helping to reduce the energy consumption of the network device for charging the terminal.

[0046] In some possible implementation manners of this method, this at least one type of energy may include at least one of the following types of energy: radio frequency energy, light energy, thermal energy, or vibration energy.

[0047] In some possible implementation manners of this method, the first information further indicates the duration and / or type of the at least one type of energy.

[0048] In some possible implementation manners of this method, the at least one type of energy includes radio frequency energy, and the first information further indicates the frequency band of the radio frequency energy.

[0050] In some possible implementation manners of this method, before sending the second information to the terminal, the method further includes: receiving third information from the terminal, where the third information is used to indicate that the terminal requests the network device to perform radio frequency energy measurement.

[0051] In some possible implementation manners of this method, the third information further indicates the operating frequency band of the terminal.

[0052] In some possible implementation manners of this method, the resources for the terminal to collect environmental energy include multiple time domain resources, and different time domain resources in the multiple time domain resources correspond to different frequency domain resources.

[0053] In some possible implementation manners of this method, the method further includes: receiving fourth information from the terminal, where the fourth information indicates a second intensity, and the second intensity is the intensity of at least one type of energy in the environment where the terminal is located, and the measurement period of the second intensity is after the measurement period of the first intensity.

[0054] In some possible implementation manners of this method, the fourth information indicates the second intensity, including: the fourth information indicates the difference between the second intensity and the first intensity.

[0055] In some possible implementation manners of this method, the absolute value of the difference between the second intensity and the first intensity is greater than or equal to a threshold.

[0056] In some possible implementations of the method, the method further includes: sending fifth information to a terminal, where the fifth information is used to configure the threshold.

[0057] In some possible implementations of the method, the resources used to receive the fourth information are pre-configured or pre-defined.

[0110] It should be noted that, Figure 1 and [[ ]] Figure 2 are simplified schematic diagrams shown only for easy understanding. In actual applications, the communication system may include multiple network devices or multiple terminal devices. The embodiments of the present application do not limit the number of network devices and terminal devices included in the communication system.

[0111] Figure 3 is a schematic flowchart of a communication method according to an embodiment of the present application. As [[ ]] Figure 3 shown, the method may include S310 and S320.

[0112] S310, the terminal sends a first piece of information to the network device, the first piece of information indicates a first intensity, and the first intensity is the intensity of at least one type of energy in the environment where the terminal is located. Correspondingly, the network device receives the first piece of information from the terminal.

[0113] S320, the network device sends an energy charging signal to the terminal according to the first piece of information. Correspondingly, the terminal receives the energy charging signal from the network device.

[0114] In this method, the terminal sends an indication of the intensity of one or more types of energy in the environment where the terminal is located to the network device, so that the network device can know the intensity of the energy that the terminal can obtain from the environment, so that the network device can determine an energy charging signal with appropriate power based on the intensity of the environmental energy, and further reduce the energy consumption of the network device for charging the terminal.

[0115] In the embodiments of the present application, the energy in the environment where the terminal is located can be understood as the energy that the terminal can obtain from the environment, which can be referred to as ambient energy (ambient energy, ambient energy harvesting, or energy harvesting), and the first information can be referred to as ambient energy information.

[0116] In the embodiments of the present application, the intensity of energy can also be referred to as the power intensity of energy.

[0117] In some implementation manners, this at least one type of energy may include at least one of the following types of energy: radio frequency energy, light energy, thermal energy, or vibration energy. Among them, radio frequency energy can be abbreviated as RF energy.

[0118] This at least one type of energy may include one type of energy or multiple types of energy.

[0119] In some implementation manners, which types of energy this at least one type of energy includes can be predefined or preconfigured.

[0120] As an example, this at least one type of energy includes one type of energy, such as including RF energy or ambient light energy or vibration energy or thermal energy. In this case, an example of the content included in the first information is as follows: "Intensity: -20dBm". This indicates that the intensity of the energy that the terminal can collect from the environment is -20dBm.

[0121] When this at least one type of energy includes multiple types of energy, in some implementation manners, the first information may separately indicate the intensity of each type of energy or indicate the total intensity of these multiple types of energy.

[0122] When this at least one type of energy includes two types of energy, such as including RF energy and light energy, an example of the first information separately indicating the intensity of each type of energy is as follows: The content included in the first information is "Intensity: -20dBm; Intensity: 20dBm". This indicates that among the two types of energy that the terminal can collect from the environment, the intensity of one type of energy is -20dBm and the intensity of the other type of energy is 20dBm.

[0123] When this at least one type of energy includes multiple types of energy, such as including RF energy and light energy, an example of the first information indicating the total intensity of these multiple types of energy is as follows: The content included in the first information is "Intensity: 10dBm". This indicates that the sum of the intensities of the two types of energy that the terminal can collect from the environment is 10dBm.

[0124] In some implementation manners of this embodiment, the first information may further indicate the duration of this at least one type of energy. The duration of energy can also be referred to as the duration time.

[0125] Optionally, the duration of each type of the at least one type of energy can be indicated separately, or the first information indicates a duration for all types of energy among the at least one type of energy.

[0126] For example, the duration indicated by the first information can be the duration of the energy with the maximum intensity among the at least one type of energy, can be the shortest duration among the durations respectively corresponding to the at least one type of energy, can be the average duration of the durations respectively corresponding to the at least one type of energy, or can be the total duration of the type of energy with the strongest intensity among the at least one type of energy.

[0127] Taking the at least one type of energy including one type of energy as an example, for example, if this type of energy is radio frequency energy or light energy, the first information may include the following content: "Intensity: -20 dBm, Duration: 1 s", where "s" represents the time unit "second". This indicates that the energy intensity of this energy source that the terminal can collect from the environment is -20 dBm and has persisted for 1 second.

[0128] Taking the at least one type of energy including multiple types of energy and the first information indicating the intensity and duration of each type of energy separately as an example, the first information may include the following content: "Intensity: -20 dBm, Duration: 1 s; Intensity: 20 dBm, Duration: 2 s". This indicates that among the multiple types of energy that the terminal can collect from the environment, the intensity of one type of energy is -20 dBm and has persisted for 1 second, and the intensity of another type of energy is 20 dBm and has persisted for 2 seconds.

[0129] Taking the at least one type of energy including multiple types of energy and the first information jointly indicating the intensity and duration of the multiple types of energy as an example, the first information may include the following content: "Intensity: 10 dBm, Duration: 1 s". This indicates that the total intensity of the multiple types of energy that the terminal can collect from the environment is 10 dBm and has persisted for 1 second.

[0130] In some implementation manners of this embodiment, the first information may further indicate the type of each type of energy among the at least one type of energy. The type of energy can also be referred to as the kind or classification of the energy.

[0131] Taking the at least one type of energy including one type of energy as an example, the first information may include the following content: "Intensity: -20 dBm, Type: Radio frequency energy". This indicates that there is radio frequency energy in the environment and the energy intensity is -20 dBm.

[0132] Taking the at least one type of energy including one type of energy as an example, the first information may include the following content: "Intensity: 20 dBm, Type: Light energy". This indicates that there is a light source in the environment and the energy intensity of the light source is 20 dBm.

[0133] Taking the example that the at least one type of energy includes multiple types of energy and the first information separately indicates the intensity and type of each type of energy, the first information may include the following content: "Intensity: -20 dBm, Type: Radio Frequency Energy; Intensity: 20 dBm, Type: Light Energy". This indicates that the terminal can collect radio frequency energy and light energy from the environment, where the intensity of the radio frequency energy is -20 dBm and the intensity of the light energy is 20 dBm.

[0134] Taking the example that the at least one type of energy includes multiple types of energy and the first information jointly indicates the intensity and type of the multiple types of energy, the first information may include the following content: "Intensity: 10 dBm, Type: Radio Frequency Energy, Light Energy". This indicates that the terminal can collect radio frequency energy and light energy from the environment, and the sum of the intensity of the radio frequency energy and the intensity of the light energy is 10 dBm.

[0135] In some implementation manners of this embodiment, the first information indicates the intensity, duration, and type of each type of the at least one type of energy.

[0136] Taking the example that the at least one type of energy includes one type of energy, the first information may include the following content: "Intensity: -20 dBm, Duration: 1 s; Type: Radio Frequency Energy". This indicates that there is radio frequency energy in the environment, with an energy intensity of -20 dBm and it has persisted for 1 second.

[0137] Taking the example that the at least one type of energy includes one type of energy, the first information may include the following content: "Intensity: 20 dBm, Duration: 1 s; Type: Light Energy". This indicates that there is a light source in the environment, with an energy intensity of 20 dBm and it has persisted for 1 second.

[0138] Taking the example that the at least one type of energy includes multiple types of energy and the first information separately indicates the intensity and type of each type of energy, the first information may include the following content: "Intensity: -20 dBm, Duration: 1 s; Type: Radio Frequency Energy; Intensity: 20 dBm, Duration: 1 s; Type: Light Energy". This indicates that the terminal can collect radio frequency energy and light energy from the environment, where the intensity of the radio frequency energy is -20 dBm and it has persisted for 1 second, and the intensity of the light energy is 20 dBm and it has persisted for 1 second.

[0139] Taking the example that the at least one type of energy includes multiple types of energy and the first information jointly indicates the intensity, duration, and type of the multiple types of energy, the first information may include the following content: "Intensity: 10 dBm, Duration: 1 s; Type: Radio Frequency Energy, Light Energy". This indicates that the terminal can collect radio frequency energy and light energy from the environment, where the sum of the intensity of the radio frequency energy and the intensity of the light energy is 10 dBm and it has persisted for 1 second.

[0140] In some implementation manners of this embodiment, when at least one type of energy indicated by the first information includes radio frequency energy, the first information may further indicate the frequency band of the radio frequency energy.

[0141] As an example, the first information may include the following content: "Intensity: -20dBm, Frequency band: 800 - 900MHz". This indicates that there is radio frequency energy in the environment with a frequency band from 800MHz to 900MHz and an energy intensity of -20dBm.

[0142] As another example, the first information may include the following content: "Intensity: -20dBm, Duration: 1s, Frequency band: 800 - 900MHz". This indicates that there is radio frequency energy in the environment with a frequency band from 800MHz to 900MHz, an energy intensity of -20dBm, and it has persisted for 1 second.

[0143] As yet another example, the first information may include the following content: "Intensity: -20dBm, Time: Persisted for 1s, Frequency band: 800 - 900MHz, Type: Radio frequency; Intensity: 20dBm, Time: Persisted for 1s, Type: Light". This indicates that there is radio frequency energy in the environment with a frequency band from 800MHz to 900MHz, an energy intensity of -20dBm, and it has persisted for 1 second; there is also light energy with an energy intensity of 20dBm and it has persisted for 1 second.

[0144] As yet another example, the first information may include the following content: "Intensity 10dBm, Time: Persisted for 1s, Types: Radio frequency, Light, Frequency band: 800 - 900MHz". This indicates that there is an energy source in the environment with an intensity of 10dBm, and the energy light and radio frequency energy including 800 - 900MHz have persisted for 1s.

[0145] In some implementation manners of this embodiment, the first information may be carried in a charging request, and this charging request is used to request charging from a network device.

[0146] In some implementation manners of this embodiment, the network device may calculate the transmission power of the charging signal based on the first information. For example, the transmission power of the charging signal is greater than or equal to the difference between the charging power required by the terminal and the intensity of the environmental energy indicated by the first information.

[0147] In some implementation manners of this embodiment, the terminal may further report at least one of the following information to the network device: remaining battery power, maximum energy storage capacity, desired charging amount, or the location information of the terminal. This information may be referred to as charging assistance information, or simply assistance information for short.

[0148] In some implementation manners, the assistance information and the first information may be carried in the same message. For example, they may be carried in the charging request.

[0149] After the network device receives the information reported by the terminal, it can determine the transmission power of the charging signal based on this information and the first information. For example, after the network device receives the remaining battery power and the environmental energy intensity, it can calculate the power for transmitting the charging signal.

[0150] An example of a calculation method is as follows: Calculate the initial required power of the charging signal based on the remaining battery power, and then subtract the environmental energy intensity from the initial required power to obtain the charging signal power. It can be seen that by knowing the environmental energy intensity, the network device can save the occupation of network device resources and only needs to compensate for a part of the energy gap.

[0151] Among them, if the first information indicates the total intensity of at least one type of energy, the environmental energy intensity subtracted from the initial required power can be this total intensity; if the first information separately indicates the intensity of each type of energy among the at least one type of energy, the environmental energy intensity subtracted from the initial required power can be the sum of the intensities of all the energies among the at least one type of energy.

[0152] In some implementation manners of this embodiment, the terminal can measure the intensity of the radio frequency energy in the environment through an antenna.

[0153] In some implementation manners of this embodiment, the terminal can measure the intensity of the light energy in the current environment through a solar panel.

[0154] In some implementation manners of this embodiment, the charging signal can be a radio frequency signal dedicated to providing charging power.

[0155] In some implementation manners of this embodiment, the terminal can measure the intensity of the vibration energy in the current environment through the electrical signal converted by a shock absorber.

[0156] In some implementation manners of this embodiment, the terminal can measure the intensity of the thermal energy in the current environment by converting it into an electrical signal through a thermoelectric material.

[0157] Figure 4 It is a schematic flowchart of the communication method according to another embodiment of the present application. As Figure 4 shown, the method may include S410, S415, and S420.

[0158] S410, the terminal sends the first information to the network device, where the first information indicates a first intensity, and the first intensity is the intensity of at least one type of energy in the environment where the terminal is located. Correspondingly, the network device receives the first information from the terminal.

[0159] This step can refer to S310 and will not be elaborated here.

[0160] S415, The network device sends charging configuration information to the terminal, and the charging configuration information indicates the charging duration and / or charging frequency of the terminal.

[0161] Among them, the charging time can be the estimated or pre-configured charging time, and can also be called the charging duration; the charging frequency can be the frequency band information of the charging signal.

[0162] S420, The network device sends a charging signal to the terminal according to the first information. Correspondingly, the terminal receives the charging signal from the network device.

[0163] This step can refer to S320 and will not be elaborated here.

[0164] Some technical effects of this method can refer to Figure 3 the technical effects of the method shown. Moreover, the network device indicating the charging duration to the terminal is beneficial for the terminal to plan the time for the next charging request; the network device indicating the charging frequency to the terminal is beneficial for the terminal to adjust the frequency matching range of hardware such as antennas and rectifiers; thus making the charging more efficient, reducing the charging time, and saving base station resources.

[0165] In some implementation manners of this embodiment, the charging configuration information indicating the charging duration of the terminal may include: the charging configuration information includes time-domain resource information and / or frequency-domain resource information allocated for the charging signal. In this implementation manner, the terminal can estimate the charging duration based on the time-domain resource information and can determine the charging frequency range based on the frequency-domain resource information.

[0166] It can be understood that Figure 4 the method shown may also include Figure 3 one or more steps other than S310 and S320 in the method shown.

[0167] Figure 5 is a schematic flowchart of a communication method according to another embodiment of the present application. As Figure 5 shown, the method may include S508, S510, and S520.

[0168] S508, The network device sends second information to the terminal, and the second information is used to determine the resources for the terminal to collect ambient energy. Correspondingly, the terminal receives the second information from the network device.

[0169] The resources for the terminal to collect ambient energy can meet the following characteristics: The network device does not send signals on these resources.

[0170] S510, The terminal sends first information to the network device, and the first information indicates a first intensity, where the first intensity is the intensity of at least one type of energy in the environment where the terminal is located. Correspondingly, the network device receives the first information from the terminal.

[0171] This step can refer to S310 and will not be elaborated here.

[0172] S520. The network device sends a charging signal to the terminal according to the first information. Correspondingly, the terminal receives the charging signal from the network device.

[0173] This step can refer to S320 and will not be elaborated here.

[0174] Some technical effects of this method can refer to Figure 3 the technical effects of the method shown. Moreover, this method helps the energy intensity collected by the terminal not to be interfered by the intensity of the radio frequency signal of the network device, so as to improve the accuracy of the environmental energy intensity collected by the terminal, and further better save the resource energy consumption of the network device.

[0175] In some implementation manners, the resources for the terminal to collect environmental energy do not include the resources where the network device sends signals on the entire working frequency band of the terminal. Or rather, the network device does not send signals on some or all of the frequency domain resources in some time domain resources, and the second information indicates the time-frequency resources and the frequency domain resources. The terminal collects environmental energy information at the resources indicated by the second information.

[0176] In some implementation manners of this embodiment, the resources for the terminal to collect environmental energy include multiple time domain resources, and different time domain resources among these multiple time domain resources correspond to different frequency domain resources. Or rather, at different time domain resources, the network device turns off different partial frequency bands, which can reduce the impact of environmental energy measurement or collection on other services other than the charging service of the network device.

[0177] For example, when the energy collection frequency band range of the terminal is very large, if the network device turns off all frequency bands in some time slots, this will seriously affect other services of the network device. Therefore, at this time, some time-frequency resource patterns are needed to ensure that the terminal can measure the environmental energy of different frequency bands in a time-division manner. The time-frequency resource pattern can be adjusted according to the energy collection frequency band of the terminal.

[0178] Figure 6 is an example pattern of time-frequency resources. Figure 6 In, from the frequency domain direction, one grid can be one frequency band; from the time domain direction, one grid can be one time slot.

[0179] Such as Figure 6 shown, different time slots turn off a part of the frequency bands, and the terminal can measure in sequence according to the configuration and finally obtain the total environmental radio frequency energy intensity.

[0180] It can be understood that the patterns of the above time-frequency resources are just examples. When the network device has little traffic, it is also possible to choose to turn off all frequency bands in some time slots. Or, when the energy harvesting frequency band range of the terminal is relatively small, the relevant frequency bands can be turned off in one or several time slots.

[0181] In some implementation manners of this embodiment, S506 may further be included, that is, the terminal sends third information to the network device, and the third information is used to instruct the terminal to request the network device to perform radio frequency energy measurement. Or it can be said that the third information is used to request the terminal to collect resources of ambient energy. Or it can be said that the third information is a radio frequency energy measurement request. Or it can be said that the third information is used to inform the network device that "the terminal needs to measure ambient energy" or "the terminal needs to measure ambient radio frequency energy".

[0182] In this implementation manner, the network device may send second information to the terminal based on the third information.

[0183] In some implementation manners of this embodiment, S504 may further be included, that is, the terminal instructs the network device of the working frequency band of the terminal. As an example, the working frequency band may be the working frequency band of circuits such as the rectifier and / or antenna of the terminal, or may be the frequency band for the terminal to collect radio frequency energy.

[0184] Optionally, the terminal instructs the network device of its working frequency band when it needs to measure ambient energy; it may also report its working frequency band to the network device when it accesses the network device. For example, the terminal carries information about the working frequency band in the message reporting the terminal capabilities.

[0185] When the terminal instructs the network device of its working frequency band when it needs to measure ambient energy, in some implementation manners, the indication information of the working frequency band and the third information may be carried in the same message, or the third information further includes the indication information of the working frequency band of the terminal.

[0186] It can be understood that in some implementation manners of this embodiment, S504 and S506 may be included simultaneously, or only one of them may be included.

[0187] It can be understood, Figure 5 One or more steps other than S410 and S420 may further be included in the method shown Figure 4 in the method shown.

[0188] Due to the randomness of environmental energy, during the charging process, the environmental energy may suddenly increase or suddenly decrease. At this time, it is necessary to timely adjust the power intensity of the charging signal. In some embodiments of the present application, the network device can dynamically adjust the charging resources during the charging process. Among them, the network device can timely adjust the charging resources according to the change of environmental energy, so as to achieve a more flexible adjustment of charging resources and more efficiently save the charging resources of the network device.

[0189] Figure 7 It is a schematic flowchart of a communication method according to another embodiment of the present application. As Figure 7 shown, the method may include S710, S720, S730, and S740.

[0190] S710, the terminal sends a first piece of information to the network device. The first piece of information indicates a first intensity, and the first intensity is the intensity of at least one type of energy in the environment where the terminal is located. Correspondingly, the network device receives the first piece of information from the terminal.

[0191] This step can refer to S310 and will not be elaborated here again.

[0192] S720, the network device sends a charging signal to the terminal according to the first piece of information. Correspondingly, the terminal receives the charging signal from the network device.

[0193] This step can refer to S320 and will not be elaborated here again.

[0194] S730, the terminal sends a fourth piece of information to the network device. The fourth piece of information indicates a second intensity, and the second intensity is the intensity of at least one type of energy in the environment where the terminal is located. Correspondingly, the network device receives the fourth piece of information from the terminal.

[0195] This step can refer to S310. For example, replace the first intensity in S310 with the first intensity, and replace the first piece of information therein with the fourth piece of information.

[0196] S740, the network device sends a charging signal to the terminal according to the second piece of information. Correspondingly, the terminal receives the charging signal from the network device.

[0197] This step can refer to S320. For example, replace the first piece of information in S320 with the fourth piece of information.

[0198] In this method, the terminal updates the intensity of the energy in its own environment to the network device. The network device can timely adjust the charging resources according to the change of environmental energy, so as to achieve a more flexible adjustment of charging resources and more efficiently save the charging resources of the network device.

[0199] In this embodiment, the moment when the terminal collects the first intensity may be referred to as the first moment, and the moment when the terminal collects the second intensity may be referred to as the second moment, and the second moment may be after the first moment.

[0200] In some implementation manners of this embodiment, the resources used to transmit the fourth information may be interspersed in the time-frequency resources of the charging signal sent by the transmission network device based on the first information. Figure 8 It is an exemplary pattern of the time-frequency resources for updating environmental energy information in an embodiment of this application.

[0201] Optionally, the resources used to transmit the fourth information may be predetermined by the communication protocol, or may be predefined between the network device and the terminal, or may be configured by the network device for the terminal through information.

[0202] When the network device configures the resources for transmitting the fourth information for the terminal through information, in some implementation manners, the network device may configure the resources for transmitting the fourth information in the configuration information of the transmission resources of the charging signal for the terminal for the first time.

[0203] For a frequency division duplexing (FDD) system, in some implementation manners, the uplink resources for transmitting the fourth information and the charging resources may be in the same time slot.

[0204] For a time division duplexing (TDD) system, in some implementation manners, the charging resources and the uplink resources are in different time slots.

[0205] When the fourth information indicates the second intensity, in some implementation manners, the fourth information may indicate the difference between the second intensity and the first intensity. In this way, the transmission overhead can be reduced.

[0206] As an example, if the first intensity is 10 dBm and the second intensity is 5 dBm, then an example of the fourth information is "Intensity: -5 dB". This means that the current environmental energy is reduced by 5 dB, indicating that the environmental energy becomes weaker.

[0207] As another example, if the first intensity is 10 dBm and the second intensity is 5 dBm, then an example of the fourth information is "Intensity: 5 dB". This means that the current environmental energy increases by 5 dB, indicating that the environmental energy becomes stronger.

[0208] In this embodiment, S710 and S720 may be collectively referred to as an environmental energy reporting stage, and S730 and S720 may be collectively referred to as an environmental energy reporting stage. Among them, during one charging process of the terminal and the network device, the first environmental energy reporting stage is called the first stage, and the subsequent environmental energy reporting stages may be called the update stages.

[0209] The fourth piece of information may indicate how the difference between the second strength and the first strength is realized. The network device may determine whether the current strength is an absolute strength value or a relative strength difference based on whether it is the first stage or the update stage.

[0210] In some implementation manners of this embodiment, during the update stage, the terminal may report the fourth piece of information only when the absolute value of the difference between the second strength and the first strength is greater than or equal to a threshold. Or rather, when the absolute value of the difference between the second strength and the first strength is less than the threshold, the terminal does not report the fourth piece of information.

[0211] In some implementation manners, this threshold may be agreed upon between the network device and the terminal.

[0212] As an example, when the terminal accesses the network device, the network device may configure this threshold through a radio resource control (RRC) message.

[0213] As another example, after the terminal sends a charging request to the network device, the network device configures this threshold through a downlink message. For example, this threshold may be sent to the terminal in the same message as the charging configuration information.

[0214] The terminal reporting the fourth piece of information only when the absolute value of the difference between the second strength and the first strength is greater than or equal to the threshold can implicitly inform the network device of the current environmental energy change situation.

[0215] As an example, when it is agreed between the network device and the terminal that the energy change is greater than 5 dB or less than -5 dB, the terminal reports the environmental energy, which can save the power of the terminal and reduce the complexity of interaction.

[0216] For another example, if the environmental energy strength in the first stage is 10 dBm and the environmental energy strength in the update stage is 3 dBm, then the energy change is -7 dBm. Since the energy change amount is less than the threshold of -5 dB, it should be reported to the network device.

[0217] It can be understood that Figure 7 the method shown may further include Figure 5 one or more steps other than S510 and S520 in the method shown.

[0218] Figure 9 is a schematic flowchart of a communication method according to another embodiment of this application. As Figure 9 shown, this method may include S910, S920, S930, and S940.

[0219] S910, the terminal sends first information to the network device, where the first information indicates a first intensity, and the first intensity is the intensity of at least one type of energy in the environment where the terminal is located. Correspondingly, the network device receives the first information from the terminal.

[0220] This step can refer to S310 and will not be elaborated here.

[0221] S920, the network device sends an energy charging signal to the terminal according to the first information. Correspondingly, the terminal receives the energy charging signal from the network device.

[0222] This step can refer to S320 and will not be elaborated here.

[0223] S930, the terminal sends fourth information to the network device, where the fourth information indicates a second intensity, and the second intensity is the intensity of at least one type of energy in the environment where the terminal is located. Correspondingly, the network device receives the fourth information from the terminal.

[0224] This step can refer to S310. For example, replace the first intensity in S310 with the first intensity, and replace the first information therein with the fourth information.

[0225] S940, the network device sends sixth information to the terminal, where the sixth information indicates the end of energy charging.

[0226] In this embodiment, when the network device receives the updated environmental energy information, it can further make a decision. If it is found that the current environmental energy is very strong and the network device no longer needs to actively charge, it can send a message to terminate the charging to the terminal, ending this process, thereby saving the charging resources of the network device.

[0227] It can be understood that Figure 9 the method shown may further include Figure 7 one or more steps other than S710, S720, and S730 in the method shown. For example, when the second intensity is less than or equal to the intensity threshold, the network device can execute S740.

[0228] Figure 10 is a schematic flowchart of a communication method according to another embodiment of the present application. As Figure 10 shown, the method may include S1010, S1020, and S1030.

[0229] S1010, the terminal sends first information to the network device, where the first information indicates a first intensity, and the first intensity is the intensity of at least one type of energy in the environment where the terminal is located. Correspondingly, the network device receives the first information from the terminal.

[0230] This step can refer to S310 and will not be elaborated here.

[0231] S1020: The network device sends a charging signal to the terminal according to the first information. Correspondingly, the terminal receives the charging signal from the network device.
